Sony's cinema-style full-frame mirrorless — A7S III internals in a compact Cinema Line body with active cooling.
The Sony FX3 (ILME-FX3) was released in 2021 as the Cinema Line full-frame camera in a compact stills-camera body form, featuring a full-frame BSI Exmor R CMOS sensor and 4K/120fps internal recording. 5-axis IBIS (5.5 stops). Dual base ISO (800 and 12800) for clean high-ISO cinematography. NP-FZ100 battery. At approximately 715g with battery. Sony FE full-frame mount.
Full-frame BSI Exmor R CMOS (12.1MP stills / 10.2MP video). 4K up to 120fps internal (XAVC HS H.265 up to 200 Mbps; XAVC S-I H.264 All-Intra up to 600 Mbps at 60p); 10-bit 4:2:2 internal. 5-axis IBIS 5.5 stops. Dual base ISO (ISO 800 / ISO 12800). NP-FZ100 battery. Approximately 715g with battery. Sony FE full-frame mount.
The FX3's compact stills-camera body format distinguishes it from the FX6 and FX9 cinema bodies: the FX3 uses the same sensor and IBIS as the Sony A7S III in a Cinema Line form with XLR handle included, making it the Cinema Line option for operators who need a small-body setup. The dual base ISO reflects the A7S III's sensor lineage — clean high-ISO at ISO 12800 is a primary use case.
On the used market the Sony FX3 is available at Cinema Line pricing. Condition checks: IBIS operation, 4K/120fps recording function, NP-FZ100 battery health, XLR handle unit condition. Compatible with all Sony FE-mount lenses.
